If brought into production, the drilling, access roads and pumping stations could cause exten- sive degradation to the natural habitat in the area. Other potential threats result from activities that are permitted in the Agriculture Land Reserve. The private property where C. tenella occurs is in the Agricultural Land Reserve, where primary land use is agriculture. For instance, some types of till/soil removal are allowable without application to the Agricultural Land Commission (Provincial Agricultural Land Com- mission 2003*). On these lands, development pressures may not appear to be an issue at this time. The Agri- cultural Land Reserve status may prevent subdivision development, but does allow other activities that could also potentially threaten the populations. In recent years many tracts of Agricultural Land Reserve land in southern British Columbia has been converted to housing developments, shopping malls and golf cours- es, either by decisions of the Agricultural Land Com- mission or very rarely by an 'order in council" by the sitting provincial legislature. Another threat likely to have a negati\e impact is recreational off-road vehicle use. The authors obser\ed evidence of all-terrain vehicles and dirt bike use in the area of the sites in 2002. The steep and relatively unsta- ble slopes where C. tenella occurs are highly suscep- tible to disturbance but at the same time, present a desirable challenge for off-roaders. Although weeds are not a major threat to C. tenella populations, weed control acti\ ities do constitute a minor potential threat to populations. Under the Weed Control Act. an occupier must control noxious weeds growing or located on land an
